Per-O-benzylated ethyl 5-N-acetyl--thiosialoside 1 was synthesized and its reactivity as a sialyl donor was investigated. It was demonstrated that the reactions of 1 with various primary and secondary alcohol acceptors, including monosaccharides, gave good to excellent yields (53-92%) and acceptable to excellent -selectivity (:=2 approximate to 10:1) , showing its promise for application to sialoglycan synthesis.
